On saturday night sucked my boyfriends penis, and now its sunday night and im urinating alot more than i usually do. Is that a sign i have a std? If so, which one?

I had a condom slip off once during sex, and duing my next period I had worse cramps than normal. Is this a possible sign of an std? If so, which ones?

You don’t need to tell me to get tested, I am planning on it. But I was just wondering if you know this to be a symptom or if there could be another cause.
